Here are a couple of cool apps for readers. First we have the Louisville Free Public Library's mobile app. Search the catalog, reserve or renew items, check your account, and see what's happening at the library. Follow us on Facebook and Twitter, ask staff questions – all at the touch of a button and all for FREE.The second app is from YALSA(Young Adult Library Services Association). Search for books by title, genre, award, or list or create your own reading list. You can also use the app to find the book at a local library. It is called Teen Book Finder .
